Abstract: The present invention relates to a resin guardrail consisting of a resin composition containing polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (ABS) and fixed to a vertical post (P) and, more particularly, relates to a resin guardrail having improved durability and impact resistance, the resin guardrail being produced through extrusion molding of the resin composition containing polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (ABS) and made by mixing 1 to 10 parts by weight of microcapsules containing acrylic acid (CH2=CHCOOH), hydrogen peroxide (H2O2), lithium nitrate trihydrate (LiNO33H2O), and acrylonitrile (CH2CHCN), based on 100 parts by weight of resin mixture containing the PVC compound and the ABS compound mixed at a weight ratio of 50:50 to 90:10.
